With the XD Design Bobby Anti-theft 15-inch Backpack, you'll outsmart thieves. The compact backpack, for both women and men, is made of a cut-resistant material, making it more difficult for pickpockets to cut your bag open. The bag also features hidden zipper closures and secret pockets, making it more difficult for strangers to get to your things. The bag has separate compartments for your 15.6-inch laptop and tablet, allowing you to easily transport your devices. You can also charge your smartphone when you're on the go, thanks to the handy USB charging port. The bag also has a trolley sleeve, which is a great help if you frequently travel. The reflective strips ensure better visibility in the dark.Note: the size of your laptop, like 15-inch or 17.3-inch, is the screen size, not your whole laptop. If your laptop has wide bezels around the screen, it's better to choose a laptop compartment that's a size bigger. That way you'll know for sure that your laptop fits.
